Phonon Hall effect (PHE) has attracted a lot of attention in recent years with many theoretical and experimental explorations published. While experiments work on complicated materials, studies are still hovering around the phenomenon-based models. Moreover, previous microscopic theory was found unable to explain large thermal conductivity obtained by strontium titanate (STO). Therefore, an att...

Discoveries of topological states and materials have reshaped our understanding physics over the past 15 years. First-principles calculations had an important role in bridging theory topology experiments by predicting realistic materials. In this Review, we offer overview first-principles methodology on quantum First, unify different concepts same band inversion scenario. We then discuss using ...
